Images have surfaced of Melissa Reid, of Lenzie, East Dunbartonshire, and Michaella McCollum Connolly, from Northern Ireland, both 20, posing happily on holiday in the capital Lima, which appeared at odds with their claims to have been coerced by Columbian gangsters at gunpoint.
There were also claims Melissa regularly partied with a convicted gangland figure in San Antonio, Ibiza, during the summer.
Melissa and Michaella are spending a third week in custody following their arrests at Lima airport as they attempted to board a flight to Madrid with £1.5 million of the drug.
After visiting his client yesterday, Peter Madden, a solicitor who played a key role in the Bloody Sunday Inquiry said: "I've had a brief meeting with Michaella. She's fine, but I told her about some of the speculative press reports. She said 'they are not true.' She said some of them are nonsense."
He also described the reports as 'bizarre.'
Mr Madden added: "At the moment we don't know if she is going to be charged."
Mr Madden later emerged from the police headquarters in Lima's San Isidro district with Michaella's brother and got into a taxi.
Melissa's anguished looking father William Reid, who has raised questions about their apparent composure in the images, later separately went into the building.
Michaella is thought to be planning to plead not guilty to drug smuggling. Melissa's plans are less clear cut, although Mr Reid has also raised questions about whether the girls were under duress when the photographes were taken.
If convicted, the pair face jail sentences of anything between six and 15 years. The latter is the minimum tariff for anyone caught with more than 10 kilogrammes of drugs.
With their first court appearance not expected for another month, there was rising speculation last night that they will be transferred within days to the Piedras Gordas 2 prison in Ancon, north of Lima
It is thought the prison where most foreign alleged drug smugglers are taken, Santa Monica Chorrillos, south of Lima, is full.
Piedras Gordas, described as a modern facility, is divided into male and female sections. The male section houses the jailed former Peruvian president Alberto Fujimori and the leader of the Shining Path movement Abimael Guzman.
